Thomas Edison
Thomas Alva Edison (February11, 1847October18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric Incandescent light bulb, light bulb, have had a widespread impact on the modern industrial society, industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical ...

Milan, Ohio
Milan ( ) is a village in Erie and Huron counties in the U.S. state of Ohio. The population was 1,371 at the 2020 census. It is best known as the birthplace and childhood home of Thomas Edison. The Erie County portion of Milan is part of the Sandusky metropolitan area, while the Huron County portion is part of the Norwalk Micropolitan Statistical Area. History and culture Milan village was platted by Ebenezer Merry in 1817 on the site of a previously abandoned Moravian Indian mission village, named " Petquotting", (1805-1809). Merry dammed the Huron River below the village and established "Merrys Mills", a gristmill and sawmill in the river valley. Milan village, originally named 'Beatty', was incorporated as 'Milan' in 1833, named after Milan, Italy. Prior to the advent of railroads, regional farmers had to bring their harvests to Lake Erie ports by wagon. The sandy and wet prairies north and west of Milan were not easily crossed by a wagon with a heavy harvest load. B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mina Miller Edison
Mina Miller Edison (July 6, 1865 – August 24, 1947) was an American community activist and the second wife of inventor and industrialist Thomas Edison. She was a community activist in Fort Myers, Florida, known for her work advancing the use of public spaces and education initiatives. Early life Mina Miller was born on July 6, 1865, in Akron, Ohio to inventor and industrialist Lewis Miller and homemaker Mary Valinda Alexander. She was the seventh of eleven children. Through her lifelong involvement with the Chatauqua Association, of which her father was a founder and leader, Mina spent the summers at Chautauqua from the age of 9 to her marriage to Edison. There a young Mina came in contact with many progressive orators, male and female who were interested in education reform, temperance, and women's suffrage. She graduated from Akron High School in 1883 and then went on to study at Mrs. Johnson's Finishing Seminary in Boston. Marriage to Thomas Edison and children Mina M ...

Research Laboratory
A research institute, research centre, or research organization is an establishment founded for doing research. Research institutes may specialize in basic research or may be oriented to applied research. Although the term often implies natural science research, there are also many research institutes in the social science as well, especially for sociological and historical research purposes. Famous research institutes In the early medieval period, several astronomical observatories were built in the Islamic world. The first of these was the 9th-century Baghdad observatory built during the time of the Abbasid caliph al-Ma'mun, though the most famous were the 13th-century Maragheh observatory, and the 15th-century Ulugh Beg Observatory. The Kerala School of Astronomy and Mathematics was a school of mathematics and astronomy founded by Madhava of Sangamagrama in Kerala, India. The school flourished between the 14th and 16th centuries and the original discoveries of the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Society
In sociology, an industrial society is a society driven by the use of technology and machinery to enable mass production, supporting a large population with a high capacity for division of labour. Such a structure developed in the Western world in the period of time following the Industrial Revolution, and replaced the agrarian societies of the pre-modern, pre-industrial age. Industrial societies are generally mass societies, and may be succeeded by an information society. They are often contrasted with traditional societies.S. Langlois, Traditions: Social, In: Neil J. Smelser and Paul B. Baltes, Editor(s)-in-Chief, ''International Encyclopedia of the Social & Behavioral Sciences'', Pergamon, Oxford, 2001, pages 15829-15833, , Online/ref> Industrial societies use external energy sources, such as fossil fuels, to increase the rate and scale of production. The production of food is shifted to large commercial farms where the products of industry, such as combine harvesters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incandescent Light Bulb
An incandescent light bulb, also known as an incandescent lamp or incandescent light globe, is an electric light that produces illumination by Joule heating a #Filament, filament until it incandescence, glows. The filament is enclosed in a glass bulb that is either vacuum, evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external Regulator (automatic control), regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, an ...

Motion Picture Camera
A movie camera (also known as a film camera and cine-camera) is a type of photographic camera that rapidly takes a sequence of photographs, either onto film stock or an image sensor, in order to produce a moving image to display on a screen. In contrast to the still camera, which captures a single image at a time, the movie camera takes a series of images by way of an intermittent mechanism or by electronic means; each image is a ''frame'' of film or video. The frames are projected through a movie projector or a video projector at a specific frame rate (number of frames per second) to show the moving picture. When projected at a high enough frame rate (24 frames per second or more), the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture. History A forerunner to the movie camera was the machine invented by Francis Ronalds at the Kew Observatory in 1845. A photosensitive surface was drawn slowly past the ape ...

Phonograph
A phonograph, later called a gramophone, and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of sound. The sound vibration Waveform, waveforms are recorded as corresponding physical deviations of a helical or spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a ''Phonograph record, record''. To recreate the sound, the surface is similarly rotated while a playback #Stylus, stylus traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a Diaphragm (acoustics), diaphragm that produced sound waves coupled to the open air through a flaring Horn loudspeaker, horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison; its use would rise the following year. Alexander Graham Bell's Volta Laboratory an ...

Sound Recording
Sound recording and reproduction is the electrical, Mechanical system, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustics, acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Communication
Mass communication is the process of imparting and exchanging information through mass media to large population segments. It utilizes various forms of media as technology has made the dissemination of information more efficient. Primary examples of platforms utilized and examined include journalism and advertising. Mass communication, unlike interpersonal communication and organizational communication, focuses on particular resources transmitting information to numerous receivers. The study of mass communication is chiefly concerned with how the content and information that is being mass communicated persuades or affects the behavior, attitude, opinion, or emotion of people receiving the information. Narrowly, mass communication is the transmission of messages to many recipients at a time. However, mass communication can be broadly understood as the process of extensive circulation of information within regions and across the globe. From a critical perspective, mass communicatio ...

Electric Power Generation
Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery ( transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method. Consumable electricity is not freely available in nature, so it must be "produced", transforming other forms of energy to electricity. Production is carried out in power stations, also called "power plants". Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission, but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are exotic and speculative methods to recover energy, such as proposed fusion reactor designs which aim to directly extract energy from intense magnetic fields generated by ...

The Economist
''The Economist'' is a British newspaper published weekly in printed magazine format and daily on Electronic publishing, digital platforms. It publishes stories on topics that include economics, business, geopolitics, technology and culture. Mostly written and edited in London, it has other editorial offices in the United States and in major cities in continental Europe, Asia, and the Middle East. The newspaper has a prominent focus on data journalism and interpretive analysis over News media, original reporting, to both criticism and acclaim. Founded in 1843, ''The Economist'' was first circulated by Scottish economist James Wilson (businessman), James Wilson to muster support for abolishing the British Corn Laws (1815–1846), a system of import tariffs. Over time, the newspaper's coverage expanded further into political economy and eventually began running articles on current events, finance, commerce, and British politics. Throughout the mid-to-late 20th century, it greatl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewis Miller (philanthropist)
Lewis Miller (July 24, 1829 – February 17, 1899) was an American businessman and philanthropist who made a fortune in the late 19th century as inventor of the first combine (harvester-reaper machine) with the blade mounted efficiently in front of the driver, to the side of the horse(s), rather than pulled behind. His daughter Mina (1865–1947) married fellow Ohio inventor Thomas Alva Edison on February 24, 1886. Biography Miller was born in Greentown, Ohio. He devoted much of his wealth to public service and to charitable causes associated with the Methodist Episcopal Church, and was the inventor of the " Akron Plan" for Sunday schools, a building layout with a central assembly hall surrounded by small classrooms, a configuration Miller conceived with Methodist minister John Heyl Vincent and architect Jacob Snyder. The arrangement accommodated 1) a collective opening exercise for all the children; 2) small radiating classrooms for graded instruction in the uniform less ...
